IMPROVEMENT IN FEED-WATER HEATERS AND FILTERS.

Specification forming part of Letters Patent No. 179,966, dated July 18,1876; application tiled Apri14, 1876.

To all whom 'it may concern:

Be it known that I, SAMUEL A. SHOAFF,0` Pennville, in the county of Jayand State ot' Indiana, have invented a new and Improved Feed-WaterHeaterv and Filter, otl w-hich the following is a specification:

In the accompanying drawing, Figure 1 represents a vertical longitudinalsection on line c c, Fig. 2, ot' myimproved feed-water heater andfilter; and Fig. 2 is a top view ofthe same with upper cover or liddetached.'

Similar letters ot' reference indicate corresponding parts.

The invention relates lto an improved feedwater heater and lilter, inwhichthe water is first thoroughly heated up by steam while passing in atortuous course through the heater, so as to deposit the lime and thenconvey the water to the filtering-receptacle below, where the water isconducted through the compartments without being' agitated by the steam.

The invention consists otl a feed-water heat- Ver arranged above afilter, the heater being made ot' inclined sections, with lateral steamtubes or passages, that extend alternately from one side to somedistanceot' the other side, to conduct the water laround the same. Thewater is conveyed through a connecting-pipe to the filter, that isprovided with entrance and exit chambers and filtering compartments,separated by vertical partitions having alternate openings at the top orbottom.A

In the drawing, A represents the feed-waterv the steam for heating upthe same entersv through a pipe, E, at the opposite side and,y lowerpart ofthe heater, and passes up throughopenings and tubes B of thesections or pans B, so as to surround the water from all sides andexercise a heating iniuence on the same.

The steam-tubes B extend alternately from one side ot' the section orpan to some distance lmore effective filtering obtained.

from the other side, so that the water iscompelled to pass in acircuitous course around the same. The different sections are secured,by suitable heel bearings or shoes and top keys, securely in the heater,and furnish to the water an increased amount of contact-surface with thesteam, so as to produce a superior capacity, and, by the ready detachingot the pans, a convenient arrangement for cleaning the heater. flhesteam leaves the heater through the exit-pipe E at the upper side,

' opposite the entrancepi pe, after having circufrom exerting any morethan a tritling forceup.

on the water, so as to prevent the dashing ofthe water over the iirstdivision at each pulsation of the steam from theY engine. The effect ofthe pulsations ot' the steam and the constant agitation ot' the water inthe filter is thereby prevented, and, by the quiet passage ot' the waterthrough the tilteringcompartments, a

rIhe water passes from the entrance-compartment to thefilteri11g-compartments that are formed by lateral partitions D1, withalternate top and bottom openings or passages, for the passage ofthewater from-one compartment to the next adjoining one. A suitablefiltering material is supported on raised-bottom screens, D2, and thelter readily cleaned by taking olf the loose cover, the space betweenheater and filter giving convenience of access to the compartments.Bottom plugs a serve to draw oit' any sediments in the same. A smallexitchamber, G', with discharge-pipe F', is arranged symmetrically tothe entrance-chamber at the opposite end ofthe filter, but withoutfiltering material in thesame.

The ready and quiet passage ot' the heated water through thefiltering-compartment, together with the ready mode ot' cleaning theheater and iilter and the simplicity of its con Y N struction, furnishesa device of superior cacle D, having compartments Gr and raised pacityfor heating,- and filtering of feedwater screens D2, all constructed andarranged subfor steam-engines. stantially as and t'or the purposespecified.`

Having thus described my invention, I i claim as new and desire tosecure by Letters SAMUEL A. SHOAFF.
